I really like the Dehaze effect; it’s similar to clarity but the contrast adjustment isn’t quite as intense. You can also use it in the negative direction to create the appearance of fog/haze. It’s a tool that is particularly well-suited for enhancing night sky images of the Milky Way.

Adobe has also modified the Import dialog in LR, something I will investigate shortly. In the meantime, enjoy the new features. Note: the Dehaze feature is only available in Lightroom CC 2015 and will not appear in Lightroom 6.
